Wiser for KNX (LSS100100). Error connecting via Wiser KNX app

[Engine]

Hello. I use Wiser for KNX (LSS100100) and Wiser KNX app on iPhone. When i try to connect to Wiser for KNX thought  Wiser KNX app i have a warning "Something went wrong while initializing the appication. The controller seems to be offline." and there is also the ability to choose further action "Try again", "Ignore" or "Logout". The connection will not be successfully whatever i choose. This has been going on for a day already. The result is the same when I try to make connection through another iPhone. The internet connection is ok. Moreover I can connect to Wiser for KNX (LSS100100) using WEB interface and i see that it works normally and i can operate it. Of course i can restart the device and everything can be normal again, but in this case i will not actually know what was the problem and it can happen again.

This app is 100% done by SE, you should contact SE support.
PS. Make sure you did set gateway and DNS settings correctly in System-Network- interface

Check as Daniel mentioned the DNS and Default GW, next to that make sure you have create a Touch Visu with (app compatible) control items that needs to be showed in the app and make sure that all apps are updated currently -> Automations v1.0.2, Cloud connector v1.12.2,  KNX IoT 3rd Party API v1.31.4 and Touch 3 v3.17.3 and check on those apps the "update automatically" flag to be sure they are always up to date in the future.
